Components For Hybrid Vehicles: Results of the IEA Annex VII “Hybrid Vehicle” Phase III

This paper describes the experiences made inside the Annex VII “Hybrid Vehicle” Phase III of the IEA Implement Hybrid & Electric Vehicle. In particular, the paper focuses on the Components that have been investigated by the working group. The development of a vehicle with an electric traction system, like HEV has to deal with the introduction of components which are not present in Conventional Vehicle (CV), or which, even if present in CV, they must undergo modifications for an HEV application, like for instance the cooling compressor.
The working-group has singled out 4 main interesting areas which have these critical components: Fuel Converters, Drives, Energy Storage, and Auxiliaries. The issues related to these areas must be properly solved for achieving the needed HEV’s performances. Inside the Annex VII the experts have discussed it, and the paper gives an overview of this process.
